@Jmoski I agree with most everything you said above. You have the right outlook in my opinon. I am a M9 slalom skier (age 76). I have never had great athletic ability in any sport, but water skiing is so much fun for me that I did (and do) it a lot. Simple repetition and desire kept me improving. About two years ago, my performance began to decline however. I used to run -35 in almost every practice session and fairly often in tournaments. That is not happening anymore. There are at least two reasons I believe. First, my age and health have decreased my stamina and energy. I now take 4 pass sets whereas formerly it was often 6 or more. Reduced stamina and reduced practice just plain hurt tournament performances and even practice performances. But you, barring some catastrophe, should be looking forward to 15 or 20 years of improving and then maintaining. The answer to your question, i.e. the last line of your today's post, is yes.
@animal I didn't adjust my expectations until age 75. But you are correct about reflexes and strength diminishing with age. That is why AWSA slows the boat speed for older skiers. An older skier can still get into short line for example, but at 30 mph instead of 36. The buoy count is lower, but the psychology is beefed up by the fact that one is still getting into -38 or whatever. Amateur water skiing does not have the same expectations as professional sports. Think NFL football. A 75 year old there would be carried off the field in the first quarter, maybe the first play; and most old slalom skiers would likely not make an opening pass at 36 mph. I can also tell you that lowering my expectations was and IS difficult. I hate it, and hopefully I will for years to come.
